these arms extending in opposite directions and parallel to each otherwhen the throttles are closed, they being connected by pivotal link 24.In this case, when yone of them is actuated the other will besimultaneously actuated in the opposite direction to .practiy In thesefigures, parts similar to thosev of Figs. 2 and 3 are marked with the'same numerals, with a Aprime mark applied.

In both forms the gasolene feed system comprising the constant levelreservoir 15 and ldie feeds therefrom, is. attached to the air systemAby suitable lugs bolted to corresponding lugs at the side of the casting5. It will be noted that the gasolene feed supply system may be easilydetached and removed and that when the parts are assembled the feedtubes secure the Venturi tubes in place.

The advantages of my invention res-u from the symmetricalv arrangementof lthe arts -ivin two carbureters in line with only one oat chamber,andl affording a cheap and simple device which may be easily made. Theair entering through the common supply channel is split and passesv inopposite directions through the two carburetlng chambers under the,control. of the connected throttles.

Many changes may be made the form 'of the carbureters, the supplyconnections,

' etc., the supplemental air valve may be used ornot, as desired, andother changes may be made without departing from my invention.

I claim:

1. A ca-rbureting device, comprising a casing, said'casing having athrough bore, there being an air chamber intermediate the ends of saidcasing, an air supply communicating With said chamber, there being acarbureting chamber on-each side of said chamber Within the bore, a doetchambenvand gasolene feed tubes extending from said ioat said chamber,there chamber beyond the air cha mbei', valves within the bore of saidcasing,

means for supporting said float chamber on the casing, gasolene feedtubes extending from said float chamber to each carburetin chamberbeyond the air chamber, an throttle valves within the bore of saidcasing, said. throttle vi-.bres being located beyond the Venturi tubes;substantially de-' scribed.

3. A carbureting device, comprisingacas-` ing having.,r a through bore,there being kan air chamberintermediate the ends of casing, an airsupply'communicating with i being a` carbureting chamber on each side ofsaid air chamber, a Venturi tube in each carbureting chamber wit'hin thethrough bore, said casing being so arranged that the-tubes can be'entered through the ends thereof, a float. chamber,

means for supportinglsaid floatchamber on the easing, gasolene from saidfloat chamber to each carbureting throttle and means for connecting theopposite ends of said casing to the en 'ie supply channels;substantially as descri ed.

In testimony whereof, I have hereunto set my hand.k
